Stock markets have been drastically dropping during the past six weeks although sometimes crawling upward only to drop again. Today, the closing Dow Jones as over 2,000 points below February 5 with “corrections by Facebook and tech investments. While investors try to guess why stocks lose ground, today’s loss in Facebook—as much as seven percent at times—was clearly from the problems in a company working to control the win of Dictator Donald Trump (DDT) in the presidential election.

With the help of Russian oligarchs and officials, multi-billionaire Robert Mercer bought the presidency for DDT, and Mercer’s political-data firm Cambridge Analytica was instrumental in this success by targeting people’s emotional needs with information from social media. Last Friday night at the same time that AG Jeff Sessions fired Andrew McCabe, Facebook admitted that Cambridge lied about deleting Facebook user data obtained from Facebook in violation of the social network’s policies.

A detailed Facebook post stated that Russian-American psychology professor, Aleksandr Kogan, obtained 50 million Facebook users’ information in 2014 with his app “thisisyourdigitallife.” Kogan collected data from people and their friends who took that quiz. Only 270,000 people took the quiz, but Kogan gathered data on another 50 million people from network connections. He promised that the data was exclusively for research purposes and then sent the data to Cambridge Analytica for political purposes. The company funded his app for $800,000, and the Russian government also paid Kogan for his research into the psychology of specific Facebook users. Cambridge Analytica was also involved in the Leave.EU leading to the success of the Brexit vote for separating Britain from the European Union.

Cambridge’s control over voters comes from its “psychographic” targeting that creates psychological profiles to “effectively engage and persuade voters using specially tailored language and visual ad combinations” that appeal to each person on an emotional level. Kogan claimed that his data predicted individual neuroticism, political views, agreeableness, and interests in subjects such as militarism, horoscopes, and the environment that could be used for targeting voters. Cambridge built profiles by maximizing the use of “up to 5,000 data points on over 230 million American voters,” according to the company’s website.

In August 2016 when Cambridge was targeting voters without their knowledge for DDT’s campaign, Facebook said it was deleting the collected data but didn’t tell Facebook users that GOP operatives were in possession of their data. Kogan’s company Global Science Research had paid people $1 or $2 in 2014 to complete its quiz and required that they download an app and share data about themselves and their social network. Facebook let app developers access data, such as their friends’ names and personal information about both themselves and their network. In 2015, Facebook claimed to receive certification that Kogan, Cambridge Analytica, and founder of Cambridge Christopher Wylie had destroyed all data collected by the quiz. They didn’t.

Wylie, a data analyst for Cambridge, shared the company’s activities with The New York Times and London’s The Observer in addition with UK cybercrime investigators. Former employees and contractors of Cambridge maintain that the company still possesses all or most of the data. In an interview on Today this morning, Wylie said that Cambridge worked with Corey Lewandowski, DDT’s first campaign manager, and Steve Bannon in 2015. Wylie described the method that Cambridge used:

“This data was used to create profiling algorithms that would allow us to explore mental vulnerabilities of people and then map out ways to inject information into different streams or channels of content online so that people started to see things that may or may not be true. This is a company that took fake news to the next level.”

“Suspended by Facebook. For blowing the whistle. On something they have known privately for two years.”

Tracking responses to social media messages in real time showed the locations where DDT should go and the words that his audience would want to hear. Bannon said just before DDT’s election:

“I wouldn’t have come aboard, even for Trump, if I hadn’t known they were building this massive Facebook and data engine. Facebook is what propelled Breitbart to a massive audience. We know its power.”

Theresa Hong, an IT member of DDT’s campaign, told BBC in an interview last year, “Without Facebook, we wouldn’t have won.” She explained how a working mother could be targeted with information about child care instead of war with a more “warm and fuzzy” ad without DDT’s voice. She said, “It wasn’t uncommon to have about 35 to 45 thousand iterations of these types of ads everyday.”

Cambridge emerged in Robert Mueller’s investigation last December through its employee emails that revealed the FEC violations about non-U.S. people working on political campaigns. Cambridge’s CEO, Nix, is British, and many of the company’s employees are European or Canadian. In its Russian connections, Cambridge contacted WikiLeaks founder Julian Assange in June 2016, and the DDT campaign started paying Cambridge in July–almost $9 million by the end of the campaign.

In now-deleted tweets, Facebook’s head of security, Alex Stamos, tried to justify Kogan’s actions by stating that he “didn’t break into any systems, bypass technical controls, or use a flaw in our system to gather more data than allowed.” Yet Facebook did not permit Kogan to give data to a voter-targeting operation.

An undercover reporter has video of Cambridge CEO Nix who suggested that his company could use honey traps and bribery to discredit politicians. In defining “deep digging,” Nix said that a way to target someone is to “offer them a deal that’s too good to be true and make sure that’s video recorded” and “send some girls around to the candidate’s house…” He added that Ukrainian girls “are very beautiful, I find that works very well.” Nix said, “I’m just giving you examples of what can be done and what has been done.”

Mercer has largely stayed out of the limelight while he funds Cambridge Analytica, which keeps a shell company in the United States, and he pours his money into electing nationalist candidates. Former CEO of the investment firm Renaissance Technologies, Mercer was also a main funder of Breitbart News and the biggest donor to DDT-supporting Super PACs. Steve Bannon was VP of Cambridge Analytica while he chaired Breitbart News but quit to join DDT’s campaign. Bannon is gone from the White House, but Kellyanne Conway, close friend of Mercer’s daughter Rebecca and creator of the term “alternative news,” stayed.

Mercer used Breitbart.com as a weapon to promote negative stories about Hillary Clinton that got the most clicks and likes. He put his daughter, Rebekah, on DDT’s transition team where she picked people for top government jobs including Cabinet positions. Her push for John Bolton as Secretary of State failed, but now he’s being considered for national security adviser. She was also behind Michael Flynn’s selection for that job. On the board of Cambridge, Rebekah Mercer plans to stay there.

Elizabeth Denham, Britain’s information commissioner, plans to apply for a warrant to access Cambridge’s servers because the company has not cooperated with her investigation into its illegal activities. The EU and Democrat officials in the U.S. have joined her in demands for further investigation. Republicans, some of whom used Cambridge in their elections such as Sens. Ted Cruz (TX) and Thom Tillis (NC), are mostly staying quiet about the problem.

Cambridge Analytica wasn’t totally responsible for the loss in investment value today: under a new chairman, Jerome Powell, the Federal Reserve may raise interest rates with another two increases planned before the midterm elections. Rational influences on DDT from former Secretary of State Rex Tillerson and economic adviser Gary Cohn are gone, replaced by Mike Pompeo who wants to go to war and Larry Kudlow who is usually wrong about economics. Add to that DDT’s rabid tweets against special investigator Robert Mueller last weekend, and the nation has plunged into an uncertainty that frightens investors.
